FAMILY AFFAIR

Beverley Mitchell, husband Michael Cameron, and birthday girl, Kenzie – who turned 2 on March 28 – were joined by a tiny partygoer, Hutton (her new baby brother), for the outdoor birthday bash at Underwood Family Farms in Moorpark, California, on March 29.

COUNTRY CUTIE

Kenzie got all dressed up for the festivities, rocking a cute country party dress (from shopaddycora.etsy.com) and mini cowboy boots – which she put to very good use, running back and forth through the farm's tunnel.a

DADDY'S GIRL

The birthday girl had fun exploring all of the hands-on activities, including hanging out in this wooden play train with her dad, Michael. (Though she was afraid of the pony rides – but "we're hoping we can try again soon," Mitchell tells PEOPLE.)

QUALITY GOAT TIME

While scared of the horses, Kenzie loved petting the goats. Did her 11-week-old brother, Hutton, partake? In spirit. "Hutton was there supporting his sister, though he slept through much of the party," Mitchell tells PEOPLE. Other people who came out to support Kenzie (and who stayed awake for the festivities) were Alfonso Ribeiro and Haylie Duff.a

THE ICING ON THE CAKE

"It was a beautiful day and we had so much fun celebrating our special girl," Mitchell tells PEOPLE. "It was so fun watching her play with all her friends and get so excited about all the animals...I can't believe it has already been two years. How does that happen?"
